A lattice Boltzmann study of 2D steady and unsteady flows around a confined cylinder

Strniša, Filip (avtor), Urbič, Tomaž (avtor), Plazl, Igor (avtor)

In this work, the lattice Boltzmann (LB) method was applied to simulate incompressible steady and unsteady low Reynolds number (Re) flows around a confined cylinder. In the LB method, different collision models (Bhatnagar–Gross–Krook model, two-relaxation-time model, multi-relaxation-time model, and entropic lattice Boltzmann model) and a regularization model were used, and the results were compared. Numerical results pertaining to a two-dimensional flow around a cylinder are reported and compared with numerical and experimental data available in the literature. The results agree with the predictions made from the literature. A correlation for Strouhal number (St) for 55 ≤ Re ≤ 300 is suggested.
